To all whom it may concern:

Be it known that l, Snutun) l lln'rvnma, u citizeuof the United States,residing at Treversc City. in the county of Grand 'lravcrse and State ofMi higan, have invented certain new and useful improvements in Power-Transmitting Devices, of which the follow ing is a specification,reference being bad to the accompanying drawings.

This invention relates to improvements in power transmitting devices andmore particularly to a motor vehicle supporting device by means of whichthe motor of. an automobile or other power propelled vehicle may be usedfor operating pumps wood sawing machines, cream separators, annin millsor grain separators and various other machines. a

The invention consists of a frame or sup- ;ort on which the rear portionof an automobile or the like may be supported so that its drive Wheelswill be out of cont-act with the ground, a drive shaft arranged on theframe or support and from'which power may be transmitted to variouskinds of machines or' devices, and driving belts or other suitabledrivin connections between the drive shaft and the drive wheels of theautomobile so that the power generated by the motor of the automobilemay be trans mitted to the drive shaft and from the, latter to themachine or machines to be driven.

The invention further contemplates in; clined supports for theautomobile andlongitudinally adjustable bearing blocks on said supportswhereby the device may be adapted to accommodate automobiles ofdifferent sizes and also whereby the driving belts or connectionsbetween the drive wheels of the automobile and the drive shaft may bestretched.

The object of the invention is to provide a device of this characterwhich will be simple and practical in construction so that it may beproduced at a small cost. and will be strong and durable.

\Vith the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofarts hereinafter fully do scribed and claimed, and illustrated in theaccompanying drawings, in which--- Figure 1 is a perspective view of theim' proved power transmitting device; Fig. 2 a side elevation of thesame showing an automobile in position thereon and having its drivingwheels connected to the drive shaft; and Fig. 2; is a'dctuil \"urtlrnllongitudinal section through one of the inclin d sup )orts and itsadjustable bearing block.

'l )0 preferred embodiment of the ll'lWll lion illustrated in thedrawings comprises a support or frame 1 having at one end a horizontaltransversely extending drive shaft 2 and at its other end suitable meansfor supporting an automobile or motor vehicle with its drive wheelselevated of? of the ground or floor. While the frame or support. 1 maybe of an suitable form and construction, it preferab y consists oflongitudinal beams or sills 3 which may be secured or anchored to theground or floor nnd which are connected by cross beams 4. Rising fromthe sills 3 are uprights 5, 6 connected by inclined or diagonal braces 7and also by downwardly inclined beams or supports 8. The uprights 5 atone end of the frame are of greater height than the uprights 6 at theother end and saidu rights 5 are connected by an upper crogs bar 9 onwhich are arranged bearings v0 for the shaft 2'. The shorter upri hts 6are further strengthened by inclined races 11 arran ed between theirupper portions and the a jacent cross bar 4.

Vlhile my suitable means may be provided for holding the automobile 12upon 7 the frame or support 1 with its drive wheels 13 off of thegroumhl preferably provide on the lower ends of the inclined supportingbeams longitudinally adjustable supporting or bearing blocks 14 havingtransverse grooves 15 for the reception of the rear axle of theautomobile. Said blocks 14 are retained in position by removablo'bolts16 which pass through them and through longitudinal series of verticalopenings 17 formed in the supporting beams or bars 8, as' shown. Thebeams or supports 8 are downwardly inclined and the blocks 14 arendjustably mounted. on said beams so that the device will be adapted toreceive automobiles heving drive wheels of great or small diameter.

While any suitable means may be pro vided for impartin the motion of thedrive wheels 13 to the shaft 2, I preferably employ two endless belts 18which pass around said wheels and also around pulleys or band wheels 19fixed to the ends of the shaft- 2.

means to the machine or machines to he -that as the whee s 13 leavesizeh blocks the By employing surh drive hell's, it. will not. heneressary to alter the construction of the automobile to permit themotion ot' its motor t shaft to he imparled to the drive shalt A and Isaid lwlls may he readily tighteuml or loos eued I v adjusting thehearing hloehs l4 lun gitudiually on the inrlined heams While anysuitahle means may he provided for impartiu; the motion of the shalt 2to the machine or maehines to he driven, l preterahly provide on thecenter of the shaft i 2 a pulley or hell wheels 21) which may he 1romu-eled by a. hell it to the shaft of the marhiue or devire to hedriven.

in operalion, it will he seen that when the rear axle of the automobileor other power vehicle is plared in the grooves 15 of the hlorlis it thedrive uheols ll of the marhine are supported oll ol the ground or floorand they may he readily eouueeted hy the hells IN to the drive shaft, 3,\vhirh latter may then be connected hy the helt 2! or other driven. Theuse of the variahle speed gearing or frirtion clutch of the automobileengine or motor enables the operator to efleetively start or stop theshaft 2 and eontrol its speed according to the nature of the machinebeing driven by the device. .In order to place the rear axle of theautomobile in the grooves 15 of the supporting or hearing hloeks llwithout manually lifting the rear portion of the automobile,wedge-shaped l blocks of suitable height may be placed in 5 pro erposition, as indicated in dotted lines in l ig. 2, and the automobilemay he backed up the inclined u per faces of said hlocks so axle willlower into the grooves 15, as will be readily understood upon referenceto Fig. 2. By providing the inclined beams or sup ports 8 and arrangingthe hearing hloelcs l--l so that they may he adjusted longitudinally onsuch supports. it: will he seen that. the devire is adapted for use ineoulu-rtiou with 1 automobiles ha ring drive wheels of: dill'erent one.

While 1 have shown and described in detail the preferred muluuliment ofthe inven lion, it. will he understood that I do not, Wish to he limitedto the precise construction set forth sinee various changes in the form,proportion, arrangi-anent and. details of construetion may he resortedto without depart;- ng' from the spirit. and scope of the invent ion.

llavingr thus desrrihed the invention What claimed is:

1. The combination of an inclined frame, r lllt hearing hloelcslongitudinally adjustahle on the frame and constructed to receive andsupport. a motor vehicle with its driving wheels free. a shaft,jom'naled on the frame and means on the shaft 'l'or receiving powerj'rom the vehicle driving Wheel and transmitting the same.

9. The emnhiuation of a supporting frame having parallel upper sidebeams inclined downwardly and formed adjacent their lower ends withloruritudinal series of openings, blocks longitudinally slida-ble on theupper faees of said inclined beams and formed with openings to registerwith the openings in said heams, said blocks being also formed withtransverse grooves to re- -eive the axle of a motor vehicle and supportthe latter with its driving Wheels free, tasteuings pasod through theregisterin openings in said hlorlcs and means to a iuslahly sernre theformer upon the latter, a transverse shaft jourl'ialed upon said frameand means on the shaft for r'eceiving'power From the vehicle drivingwheel and transmitting the same.

in testimony whereof I hereunto attix my signature in the presence oftwo witnesses. REWARD FLETCHER. hi l uesses:
